FIELD OF THE ART

[0001] This invention relates to a fixing/adjusting tool of a plate material to structural body having a female member and a male member in which the female and male members are fitted to each other in an adjustable length, members are glued either to a structural body or a plate material respectively, and members set in the adjusted length are settled by adhesive. This tool is used for fixing decorative laminates or interior wood sheathings to the surface of ceilings and walls etc.

BACKGROUND ART

[0002] A method of fixing plate material is disclosed in Japanese Unexamined Patent Publication No. 1973-2932. Such a method was often used to fix the plate material or the board in which dumpling like adhesive containing water was applied to the mounting surface and the distance or space between the board and the surface was adjusted by pressing the board.

[0003] However, since this method was pointed out to be conductive to the mold growth due to a large amount of water contained in the adhesive, a fixing/adjusting tool of the Japanese Unexamined Patent Publication No. 1995-300972 was proposed in which the space adjustment is possible with a small amount of the adhesive required.

[0004] This tool comprises a member whose basal plate is provided with a tube made of thermoplastic resin having an inlet for adhesive, and a member whose basal plate is provided with a rod made of thermoplastic resin having continuous grooves on its surface, wherein the outer diameter of the rod is larger than the inner diameter of the pipe. One member is fixed to a structural body, and another member is glued to a board, and the rod is forcefully inserted into the tube, and then adhesive are injected through the inlet to set the adjusted clearance between the board and the structural body, thereby fixing the board to the structural body.

[0005] However, in this composition, it is unavoidable to adjust the clearance between the board and the structural body after inserting the rod forcefully into the pipe, much labor is necessary for pushing and pulling work for the clearance adjustment.

[0006] Further, during the fixing and adjusting the board, the adhesive must be injected between the tube and the rod through the inlet using the groove of the stick body after adjusting of the position of members. Accordingly, the size of the board is limited to be as large as the degree that the adhesive can be injected into the tools from the side edge. Therefore, it has disadvantage to be not usable to glue many tools to a large board.

[0007] This invention is directed to provide a fixing/adjusting tool of a plate material to structural body having a female member and a male member in which the female and male members are fitted to each other in an adjustable length, members are glued either to a structural body or a plate material, and members set in the adjusted length is settled by adhesive, wherein the adhesive is previously injected into the female and male members before fixing both member to the board and structural member, which enables to adjust the clearance between the board and the structural body freely.

[0008] The first aspect having the first technological mean to solve the above mentioned problem comprises (a) the female member having the base plate with the through hole in the center and the external cylinder fixed vertical to the base plate, and the male member having the base plate with the through hole in the center and the internal cylinder formed vertical to the base plate. (b) The size of the inner diameter of the external cylinder is arranged to form a gap between the inner wall of the external cylinder and the outer wall of the internal cylinder. (c) Either one member of the above members has a communicating section formed in its base plate to communicate the gap formed between internal and external cylinders and the rear surface of its base plate, and the attaching area formed at an outer periphery of the communicating section at the rear surface of the base plate. (d) Another member has a guide cylinder to guide the nozzle for injecting the adhesive formed on its base plate protruding and continuing from the through hole. (e) The front edge of the guide cylinder meet the opening edge of the through hole of one member in the contracted condition of internal and external cylinder. (f) The adhesive injected through the guide cylinder into the rear surface of the base of one member glued either to the structural body or the board, reach the gap between the internal and external cylinders through the communicating section.

[0009] The second aspect having second technological means comprises, (g) the female member having the base plate with the through hole in the center and the external cylinder fixed vertical to the base plate, and the male member having the base plate with the through hole in the center and the internal cylinder formed vertical to the base plate. (b) The size of the inner diameter of the external cylinder is arranged to form a gap between the inner wall of the external cylinder and the outer wall of the internal cylinder. (i) Either one member of the members has a guide cylinder to guide the nozzle for injecting the adhesive formed on its base plate protruding and continuing from the through hole. (j) a communicating section formed in its base plate to communicate the gap formed between internal and external cylinders and the rear surface of its flange and the attaching area formed at the outer periphery of the rear surface of the communicating section. (k) The adhesive injected through the guide cylinder into the rear surface of the base plate of one member glued to either the structural body or the board, reach the gap between the internal cylinder and external cylinder through the communicating section.

[0010] The third technological means of this invention is to modify the composition of the rear surface of the base plate of one member described in the first and the second aspects. The dish-shaped concave part having larger diameter than the periphery of the inner cylinder formed on the rear surface of the base plate of one member corresponding to the inner periphery of the internal cylinder. The communicating section that communicates the concave part and the gap between the internal and external cylinders is formed on the base plate of one member.

[0011] The fourth technological mean of this invention has projections provided on the front edge of the inside wall of the external cylinder and on the front edge of the outside wall of the internal cylinder to engage with each other. The sixth technological mean has the internal and the external cylinders having circular cross section. The fifth technological means has the small hole formed on base plate side of the internal cylinder for air release.

[0012] This invention employs a composition that the upright internal cylinder on the base plate of the male member is fitted to the upright external cylinder on the base plate of the female member forming a gap between the wall of the internal and the external cylinder.

[0013] Whichever of the female member and the male members may be glued to a structural body (building frame) or a plate material (board), the communicating section is formed on the base plate of member that is glued first either to the structural body or plate material. Further the communicating section is formed at the location corresponding to the gap that is formed between the internal and external cylinders so as to connect the rear surface of the base plate with the gap. The outer periphery of the communicating section at the rear surface of the base plate is used as the attaching area. The member is glued to the structural body or plate material by using two-sided tapes or adhesive to the attaching area. Resultantly, in the central area of the rear surface of the base, a space with the thickness of the tape or the adhesive is formed between the base plate and the structural body or the plate material.

[0014] In the base plate of the other member, the guide cylinder to guide the nozzle for injecting the adhesive connected to the through hole is formed protruding and continuing from the through hole. In the contracted condition of the internal and external cylinders, since the front edge of the guide cylinder meets the opening edge of the through hole of the base plate of the other member glued previously to the structural body or the plate material, water tightness is roughly kept between the front end of the guide cylinder and the through hole.

[0015] After one member is glued to the structural body or the plate material and the other member is fitted to one member with the internal cylinder and the external cylinders in contracted condition, the adhesive is injected through nozzle using the guide cylinder. This injected adhesive approach the rear surface of the base plate of one member passing the through hole and further reaches the gap between the internal and the external cylinder walls passing the space and the communicating section formed in the central part of the rear surface of the glued member. As the adhesive, thixotropic gelatinous agents or mayonnaise like agents are used. It is preferable to use such an agent as to be somewhat elastic after hardened to provide cushioning function to the fixing/adjusting tool.

[0016] The preparation for attaching plate material is completed, by pulling out the other member. In this stage, either of the work that is the application of the adhesive or the attachment of two-side tapes to the base plate of another member, or both of the work must be completed.

[0017] The two-sided tapes are used for the temporal tacking of boards while in the fixing work. The adhesive placed at the rear side of the base accomplishes the permanent fixing. For the temporal tacking of plate material, instantaneous adhesives can be used in place of the two-side tapes.

[0018] In the case that the fixing/adjusting tool is first glued to the structural body, the positions of base plates of one members glued to the structural body are out of alignment due to the irregularity of the structural body. And when the plate material is moved forward in an upright position, bases of other members sequentially attach and glued to the plate material corresponding to the projected positions of the structural body. By further moving the plate material forward to the desired position, base plates of other members are pushed and moved to the applied position corresponding to the position of the plate material. When the movement of the plate material is halted in the condition with desired distance from plate material and the structural body, the movement of the base plates also stops. In this condition, the adhesive charged in the gap between the internal and external cylinders are kept and adhere to the cylinder walls. The hardening of the adhesive fixes the internal and the external cylinders with settling the distance. The fixing and adjusting of the plate material to the structural body come to a complete.

[0019] As well, the plate material may be pushed strongly to the structural body once, in order to secure the bonding of the base plate to the plate material and drawn back for adjusting the position.

[0020] In the case that the fixing/adjusting tool is first glued to the plate material, the base plates of one member glued to the plate material are positioned in about equal height. And when the plate material to which the fixing/adjusting tools are applied is moved toward the structural body in its upright position, the base plates of other members adhere to the structural body according to the irregularity of the structural body. By moving the plate material forward to the desired position, the base plates of one member are pushed corresponding to the applied positions and stop at the position where the desired distance is kept. In this case also, the plate material can be pushed once strongly to the structural body in order to secure adhesion of the base to the plate material and be drawn back for adjusting the position.

[0021] In the second technical means, a guide cylinder to guide the nozzle for inletting adhesive is formed protruding on the base of the member applied first to the structural body or the plate material communicating with the through hole. In this means, since adhesive are directly injected into the rear surface of the base plate of one member, the sealing between the guide cylinder and the through hole is not a problem contrary to the above described means.

[0022] The size of the through hole of the other base plate can be as large as to pass the nozzle to the guide cylinder for inserting. Although there is a possibility of the other base plate to float due to the pressure of injected adhesive, it can be prevented by employing the injection work such as pressing down the opening edge of the through hole with the side wall of the nozzle or as pressing down the base by hand of the worker. Injection of the adhesive is not affected by the through hole being not connected to the upper edge of the guide cylinder.

[0023] The fixing procedure of plate materials to structural body is substantially the same as described above.

[0024] In the first and the second technical means, wherein., the forming of a dish-shaped concave part having a diameter larger than the periphery of the internal cylinder on the rear surface of member which is glued first to the structural body or the plate material, and the forming of a communicating section which connects the concave part with the gap between the internal and the external cylinders, allow the space between the rear surface of the base plate and the area of plate material or structural body to be made thicker than the thickness of the layer of the adhesive and the tape. It enables smooth shift of the adhesive approaching from the rear surface to the gap between the internal and external cylinders.

[0025] The providing of engaging projections protruding from the inner wall of the front edge of the external cylinder and from the outer wall of the front edge of the internal cylinder enables both projection to engage with each other in the longest state or length of the tool in retrieving one of the member from the other member. It prevents the members from splitting each other, which also prevents the departing of the internal and the external cylinders allowing smooth fixing work.

[0026] In the case that the cross section of the internal and external cylinders is shaped into circular form, it is possible to incline the base plates in the condition of the internal and external cylinders being fitted. Therefore, gluing members to the inclined plane formed by irregularity of the structural body does not interferers the plane of plate material. Further, in this type of the tool, when the layer of the structural body and the plate material are displaced due to vibration or quake, the internal and external cylinders somewhat rotates following the displacement of the layer.

[0027] In addition, the providing of a through hole on the base plate side of the internal cylinder of the male member allows air to go in and out of the member smoothly when the members are moved relatively.

[0028] In the contracted condition of the fitted internal and external cylinders, the leakage of the adhesive that passed the communicating section to the gal) can be prevented by previously fitting the front edge of the cylinder wall to the other base plate applied.

[0029] Furthermore, in order to allow the injected adhesive to move smoothly into the gap between the internal and external cylinders, it is useful to provide air release holes on the wall or on the base plate of the internal and external cylinders at the upper side (injected base plate side) of the gap. These holes have a merit that the users can indicate the completion of the charging to the gap by verifying the leakage of the adhesive through these holes. In this case, it is more useful to form at least the base plate of the member with transparent material. Resultantly, it enables to keep the track of the charging condition of adhesive visually.

[0030] As well in this case, the providing of clearances in the adhesive tapes and the adhesive agents enables to use the clearances as air release holes when the members are moved relatively.

[0031] The communicating sections formed on the base plates are formed corresponding to the gap between the internal and external cylinders, and these sections are formed at regular intervals. It allows adhesive to move into the gaps at about equal speed.

[0032] The formation of concave grooves on any one or both of the outer surface of the internal cylinder and the inner surface of the external cylinder, prevents discontinuity of adhesive and achieves secure fixing of both cylinders when the internal and external cylinders are pushed and drawn accompanying the movement of the adhesive in the condition that the gap is filled with adhesive. This concave groove can be formed in helical, lengthwise direction, lateral direction, or in combination of them.

[0033] Since this fixing/adjusting tool enables to fix the structural body and the plate material by applying the tool to the surfaces, injecting the adhesive, and moving or drawing the members, with adjusting the length or distance of both surfaces with having adhesive injected previously, high efficiency of the work are provided. And furthermore, it has a merit to provide light, work even in the case that large boards may need to be fixed to structural body or many fixing/adjusting tools may be used.

[0034] Also, it has a merit to prevent from getting moldy because of small amount of adhesive agents required.

BEST MODE FOR CARRYING OUT THE INVENTION

[0042]FIG. 1˜3 show the embodiments related to the first technical means. FIG. 1 is a central cross sectional view in the condition where the male and female members are fitted to each other. FIG. 2 is a bottom view of the female member. FIG. 3 is a bottom view of the male member.

[0043] The female member 1 and male member 11 are both made of ABS resin. However, they may be made of other resins such as acrylate resin, epoxy resin, and polyester resin etc.

[0044] In this embodiment, the female member 1 comprises the external cylinder 5 of circular cross section having the inner diameter of 49 mm and the height of 1 mm stands upright on the front surface of the base 2 whose diameter is 80 mm. The male member 11 comprises the internal cylinder 15 of circular cross section having the outer diameter of 46 mm and the height of 1 mm stands upright on the rear surface of the base 12 whose diameter is 80 mm. Accordingly, the fitting of the internal and external cylinders 15, 5 forms the gap 10 with width of 1.5 mm between the wall of the internal and external cylinders. These dimensions are designed taking the size, weight, and strength of the board to be fixed into account.

[0045] The through hole 3 for the injection of adhesive described later is provided in the center of the base plate 2 of the female member 2, and a dish-shaped concave part 4 centered on the through hole 3 is formed in the rear surface of the base plate. The outer periphery of the concave part forms the base of the external cylinder. In the inside of the outer periphery of the concave part 4, the grooves 6, 6 as communicating sections are intermittently provided on the base plate to communicate with the gap 10.

[0046]FIG. 1 shows the condition in which a two-side tape 9 is applied to the outer side of the concave part 4, where the tape is not shown in FIG. 2. In the condition that the member 1 is attached to building frames and boards which are not shown in the figure, a space whose depth is the sum of the depth of the concave part 4 and the thickness of the tape 9 is formed between the base plate and the building frame or the board.

[0047] The through hole 13 is provided in the center of the base 12 of the male member 11. The guide cylinder 14 to insert the injection nozzle of adhesive not shown in the figure is provided continuously in its rear surface. The base of the guide cylinder 14 is formed tapered to guide the nozzle in the insertion of the nozzle and to allow the guide wall to press down the male member 11 in the injection of adhesive.

[0048] In the front edge of the guide cylinder 14, the step 16 is formed, of which front edge is thinned to allow the front edge of the guide cylinder 14 to approach inside of the through hole 3 and the step 16 to press down the opening edge of the through hole 3 to keep the water-tight condition. In place of the step, a tapered wall can be employed.

[0049] The projection 8, 8 located at the inside of the upper end of the external cylinder 5 and the projection 18, 18 located at outside of the lower end of the internal cylinder 15 are formed. Each protruding prevents the splitting of the both cylinders by engaging with each other when the fitted internal and external cylinders 5, 15 are drawn.

[0050] In this embodiment, the inside of the upper end of the projection 8 and the outside of the lower end of the projection 18, 18 are formed as tapered wall to ease the fitting. The projection 8, 18 is formed four each circumferentially, but number of the projections and their intervals are designed appropriately corresponding to the size of the members. The projections may be formed like ring.

[0051] In the base plate side of the internal cylinder 15, the small hole 7, 7 for air release is provided to allow the smooth injection of adhesive and the smooth movement of air in the cavity 20 and air outside in accordance with the movement of the male member 11.

[0052]FIG. 4˜6 show the embodiments corresponding to the second technical means. FIG. 4 is a central cross sectional view of the female and male members fitted to each other. FIG. 6 is a bottom view of the female member. FIG. 6 is a bottom view of the male member.

[0053] This embodiment differs from the above describe embodiment in the point that the guide cylinder 24 is provided on the female member 1 and that the base plate of the male member is shaped in a square.

[0054] The guide cylinder 24 is formed protruding from the surface of the base plate 2 and continuing from the through hole 3, and the upper end of the guide cylinder is faced to the inside of the through hole 13 provided on the center of the base plate of the male member 11 to inject adhesive directly from there. To prevent floatage of the base plate 12 during the injection of adhesive, a collar can be provided on the adhesive injection nozzle, by which press down the base plate.

[0055] Since the inter space surrounded by the guide cylinder 24, the internal cylinder 15, the flange 2, 12 is not in a sealed condition after the injection of adhesive, there is no resistance in drawing out the male member 11.

[0056] On the base 12 of the male member 11, the small holes 17, 17 are provided along the edge. When bond is applied to the surface of the base plate 12 along the edge in order to attach the male member 11 to building frames or boards, the bond reaches the rear side passing through the holes 17 at the stage of the male member 11 being pressed against the building frames or boards achieving the anchor action by itself and improving the adhesiveness.

[0057] Next, the rotation performance test for the case of the layer between the board and the building frame been displaced is described, in which the boards are fixed to the building frames using the fixing/adjusting tools shown in FIG. 1˜3.

[0058] (Body Under Test)

[0059] Plasterboards 28 were fixed to ALC boards (Autoclaved Light-weight Concrete panel) 27 using the fixing/adjusting tool 29. Six ALC boards of the size of W600 mm×H299 mm×t100 mm were arranged in a line longwise, and were fixed to the upper and lower virtual frames 25,26 by pin joint having the mechanism which rotates with the displacement of the layer between virtual frames to form a virtual building frame.

[0060] Four plaster boards of thickness 12.5 mm×width 910 mm having length of 1820 mm were arranged in line for the lower stage of the frame, and four of those having length of 1170 mm were arranged in line for the upper stage of the frame.

[0061] The fixing/adjusting tool 29 was made by ABS resin and was attached to the ALC plate 27 and to the board 28 by thixotropic silicone adhesive. The numerals in the figure show the intervals of the fixing/adjusting tools, wherein their units are millimeter.

[0062] (Test Procedure)

[0063] The test was carried out based on the item 6.19 (Deformation performance test of assembled non-bearing panels by in-plane shearing-bending) of JIS A 1414 “Methods of performance test of panels for building construction”. A large in-plane shearing test device was used. Horizontal force was applied to the lower frame side by a hydraulic servo actuator to increase the static displacement of the layer of the test bodyon against the height of the virtual frame was gradually increased according to the cycle shown in Table 1. The sign [+] in Table 1 shows rightward, and the sign [−] shows leftward. TABLE 1 Cycle In-plane deformation angle(rad) Observation (1) 0 → + 1/400 → 0 → − 1/400 → 0 Normal (2) 0 → + 1/300 → 0 → − 1/300 → 0 Normal (3) 0 → + 1/200 → 0 → − 1/300 → 0 Joint displacement (4) 0 → + 1/150 → 0 → − 1/150 → 0 Peeling sound of the board surface paper (5) 0 → + 1/120 → 0 → − 1/120 → 0 Same as above (6) 0 → + 1/100 → 0 → − 1/100 → 0 Same as above (7) 0 → + 1/60 → 0 → − 1/60 → 0 No change

[0064] (Test Results)

[0065] To the final cycle of the static loading test, although the partial peeling off of the board surface papers to which the fixing/adjusting tools were applied was observed, no falling off of the boards and the fixing/adjusting tools nor pushing out or floating of the boards out of the surface was observed.

[0066] The ALC boards followed the deformation of the layer between virtual frames by rotation., and from the results described above., it was verified that with the rotation of the ALC plate, the plasterboards also rotated using the relative rotation between the members of the fixing/adjusting tools following the ALC boards.
